My invention relates to the manufacture of larger sized paper bagsintended. for holding' relatively heavy weights.

This bag is to be made of strong paper, and

5 I have found that in order to provide a practical bag of the charactermentioned, simple and inexpensive, but strong, closure meansspecifically a lacing should be provided for ably such lacingshould beadapted to be arranged to constitute a handle at the middle 'of the bagby whichit may be carried without tending to tear the walls of the bagat its mouth.

Further, I have found that the closure means provided should be adaptedto permit the bag to be used .over and over; in other words, the closuremeans must be adapted to permit the bag to be readily opened withouttearing the bag and thus render it worthless for further use.

Therefore the ob'ect of my invention is to providea paper ag which iseconomical I fold of substantial width, a reinforcing band being locatedin. saidfold and the opposed surfaces of said fold being cementedtogether with said reinforcing hand between them,

the arrangement ofthe bagflatwise and being provided with a series ofalined spaced holes adapted to have a lace closing the bag. 1

By such means the sides of the mouth of the bag are drawn togetherflatwise so as to distribute the strain of the weight-of the bag and itscontents evenly along the entire width of the bag and the, middleportion or loop of the lace which forms the handle serves to i hold thetwine section taut and thereby the gether.

the mouth of the bag; and further preferi of manufacture and is providedwith lacing means for closing the mouth of the bag, the laces arrangedto close the mouth of the bag sents a paper bag a made of heavy kraftpasaid reinforcement being adapted to permit,

threaded therein for sides of the mouth of the bag closely to- These andother incidental features of my invention and the details ofconstruction I thereof are hereinafter fully described with reference tothe accompanying drawing.

In the drawing:

Fig. 1 shows a perspective view of my bag and illustrates theclosu remeans and the handle formed thereby; p

Fig. 2 shows an enlarged fragmentary side .view of the mouth-of the bagillustrating how the lacing for closing the mouth of the bag isarranged, and further illustrating in broken lines how the lacing may bearranged to form its middle part into a handle for carrying the bag;

Fig. 3 shows a view of my bag looking down in the direction of the arrow3 of Fig. 2;

Fig. 4 shows a. fragmentary perspective 0 View of my bag before the laceis applied and illustrates one form of reinforcing means for the mouthof the bag;

Fig. 5 shows a perspective view of such reinforcing means removed fromthe mouth of i the bag; and I Fig. 6 shows'another form of reinforcingmeans for the mouth of my bag.

Referring now to the figures: Fig. 1 repreper or the like and preferablyof the type known as a diamond bottom bag, since this type of bagprovides a rectangular cross section when opened and thus its capacityis greater, but other types of bags may be used equally well.

The mouth I) of the bag isreinforced by folding a portion of thematerial inward as at c, Fig. 4 and in arranginga section of cord ortwine d within the crease so formed, after which. the portion 0 issecured to the body of the bag, preferably by adhesive. 3

In that way the wall section of the bag adj acent its mouth isreinforced and strengthreinforcing the mouth of the bag by substitutinga section of cardboard f or the like for the cord section (2 andsecuring the same between the portion 0 and the bag body a preferably byadhesive.

Evenly spaced holes e are punched through the reinforced walls sectionat the mouth of the bag which holes are so arranged as to register whenthe bag sides are drawn together flatwise.

The bag sides are drawn together flatwise by a lace g tied at 62 at oneend of the mouth of the bag, and then inserted thru the successive holese, in so doing, overcasting the reinforced edge of the mouth of the bag,and finally securing the free ends of the cord temporarily as at 6.

It will be evident that the described reinforcement forms semi-rigidwall sections at the mouth of the bag, adapted to provide ampleresistance to any undue strains imposed by the lace on the walls of thebag in lacing the bag shut.

If desired to arrange the lace g to form a handle as k in Fig. 1, I forman enlarged loop of the middle section of the lace as illustrated inFig. 2 by broken lines m, the handle being formed by skipping the middleholes e3, and since the mouth of the bag is reinforced and the paperfrom which it is made is heavy. The wall sections of the bag sides onwhich the strainof the lace g is imposed will not be caused to gap. Inother words, the rein forcement prevents the drawing together of thewalls of the bag from causing any collapse between the ends of the mouthof the bag. To the contrary, the semi-rigid reinforcement of the wallsections assures that the wall sections at the mouth of the bag willposed on the wall sections at the mouth of the bag, when closed bylacing, will be so evenly distributed throughout the reinforcement as toprevent the material giving way and being torn between the holes 6.

Further the closure means I- have provided may be conveniently andrapidly applied and the bag may be used over again a relatively greatnumber of times, in fact, until the bag material itself wears out;

I claim:

1. A paper bag provided at the top of two opposite sides with flaps ofsubstantial width turned over to form folds with, and cemented to thesides of the body arranged flatwise, a reinforcing band arranged andcemented in the creases of the folds so produced and extendingcompletely around the mouth of the bag, the sides of the bag directlyunder said reinforcing band being provided with a series of registeringspaced holes and a cord laced through said holes over said reinforcingband to close the mouth of the bag, and arranged to form a loopconstituting a carrying handle.

2. A paper bag provided at the top of two opposite sides with flaps ofsubstantial width turned over to form folds with, and cemented to thesides of the body arranged flatwise, a reinforcing band arrangedandmemented in the crease of the folds so produced and extendingcompletely around the mouth of the bag, the ends of said band beingbrought together under and concealed by one of said flaps, the sides ofthe bag directly under said reinforcing band being provided with aseries of registerin spaced holes and a cord laced through said holesover said reinforcing band to close the mouth of the bag, and arrangedto form a loop constituting a carrying handle.
